VENTS VUE P3B EC heat recovery air handling units

• The air handling units VUE P3B EC are the fully-featured ventilation units that ensure air filtration, fresh air supply and stale air extract.
• During the operation process the extract air heat is transferred to the supply air through the high-efficiency plate heat exchanger.
• Compatible with round Ø100 or 150 mm air ducts.

• The casing is made of polymer-coated steel panels, internally filled with polyurethane foam layer 5 or 10 mm (depending on the modification) for heat- and sound-insulation.
• This service panel is used to access the filters and the heat exchanger for maintenance operations.
• The spigots are located at the sides of the unit and are equipped with rubber seals for airtight connection to the air ducts.
• The casing is equipped with fixing brackets to suspend the unit to the ceiling.

• High-efficient electronically-commutated (EC) motors with an external motor.
• The VUE 100 P3B EC A14, VUE 150 P3B EC A14 and VUE 250 P3B EC A14 are equipped with centrifugal impellers with forward curved blades.
• The VUE 350 P3B EC A14 are equipped with centrifugal impellers with backward curved blades.
• These state-of-the-art motors are the most advanced solution in energy efficiency today.
• EC motors are characterised with high performance and optimum control across the entire speed range.
• In addition to that, the efficiency of the electronically commutated motor reaches very impressive levels of up to 90 %.

• Plate enthalpy cross-flow heat exchanger made of polymerized cellulose with heat recovery efficiency up to 85 %.
• The applied heat exchanger enables not only heat but also humidity recovery, which helps maintaining a defined humidity level.
• In warm seasons the heat exchanger operates to cool down and dehumidify the supply air.
• In cold seasons the heat exchanger operates to warm up supply air and humidify it.
• Water vapour from the humid extract air is condensed and absorbed by the heat exchanger plates.
• The recovered humidity and heat are transferred to the supply air flow.
• The air streams are fully separated within the heat exchanger and the microbes and smells are isolated.

• Due to a low casing height the air handling units are a perfect solution for space-restricted installation above suspended ceilings.
• The unit mounting position must provide access for service maintenance.

• The units are equipped with a bypass for summer ventilation (air cooling by the cool air from outside).

• Two built-in panel filters with filtering class G4 and F8 provide efficient supply air filtration.
• Extract air is cleaned by the built-in G4 filter.

• The VENTS VUE P3B EC A14 units have an integrated automation system with a wall-mounted control panel A14 with a LED indication.
• The units are equipped with a USB connector (Type B) and can be connected to a PC for configuring the advanced settings in a special software.

• The standard delivery set includes a 10 m cable for connection of the unit to the control panel.

A14 automation functions:

• Turning the unit on/off.
• Unit performance control (selection of Low, Medium or High speed).
• Bypass damper opening and closing for summer ventilation.
• Alarm indication.
• Filter replacement notification.

Additional functions of the A14 automation with installed software

• Fan speed adjustment from 0 to 100 %.
• Each speed is individually adjusted for the supply and the extract fans.
• Operation control on feedback from the HV-2 duct humidity sensor (to be ordered separately).
• Unit operation setting according to the external relay (to be ordered separately).
• Temperature setting for heat exchanger freeze protection system activation.
• Control and operation adjustment of the filter maintenance timer.
• Error code indication.
• Software version upgrading.
• External relay, bypass and humidity control.
